Inaugurated in 1903 by Marshal Cândido Rondon, military engineer and Dionísio Cerqueira, minister of state and also military engineer. Its color represents the national colors: green and yellow. On the Argentinean side the landmark is located on the banks of the Iguaçu River and on the Paraguayan on the right bank of the Paraná River.
The Paraguayan landmark was built only in 1961, rectangular in shape or in protest for the loss of the Paraguayan War (1864-1870), or for having only one face facing the river (Paraná).
Area where you can enjoy the beautiful landscape of the 3 borders, watch cultural performances of the region with light show around the obelisk. The best time to visit is in the evening at sunset.
